"Re-writable CDs. I used to burn so many mix CDs after downloading from Napster, BearShare, LimeWire, FrostWire. Then my mother would call, disconnecting the internet and I would have to start the download all over again. Except one file wasn't an mp3, but a virus. I would just reinstall windows before my mom got home as we saved every picture and document on a zip drive... then those fancy jaz drives."
